RAILWAY- MOTO R.

SPECIFICATION forming par-t of Letters Bai-.ent No. 400,522, dated April2, 1889'. Application iiled April 23, 1888. Renewed December 19, 1888.Serial No.294,ll7. (No model.)

To all whom, it may concern;

Be it known that we, JOSEPH R. VALEN- TINE and ALEXANDER T. GRIGG,citizens of the United States, residing in the city of Pueblo, in t-hecounty of Pueblo, in the State of Colorado, have invented a new anduseful Railway-Motor, of which the following is a description.

The invention relatesto that class of railway and other vehicles whichreceive locomotion from an engine which is located upon the vehicleitself. v l

The leading object of the invention is the provision of means whereby,when the engine is in operation, the vehicle may be instantly arrestedin its progress when in motion, or instantly set in motion when at restwithout arresting or retarding the movement of the engine or in any waymodifying its action.

The invention consists in the combination, with a vehicle which has twoor more pairs of supporting-wheels and an engine mounted upon thevehicle of a pair of driving-wheels which are operated by such engine,and a means whereby the driving-Wheels may either be instantly broughtinto contact with the earth or with a track-rail to impart motion to thevehicle, or whereby, when in contact, such contact may be instantlydiscontinuedv to terminate the effective action of the mpelling power.

The invention consists, also, in the connection of thedriving-wheel-operating mechanism .with the brake-operating mechanism,whereby the brakes are operated by the same mechanism by which thedriving-wheels are held in operative contact with the rail or with theroadway, or are withdrawn therefrom.

The invention consists, also, in other novel parts or combinations ofparts, as will be hereinafter described, and then distinctly claimed.

In the drawings, Figure l represents a side elevation of astreet-railway car, portions being broken out, which is provided withour improved means of propulsion. Fig. 2 isa top plan view, the body ofthe car and the brakeshaft and its support having been removed. Fig. isa perspective elevation looking' from the front toward the end of thecar. Fig. 4: is

a detail face view, drawn to an enlarged scale, of the bearing-plate andits slidinglink. Fig. 5 is a section on the line .r of Fig. 4.' Fig. 6is a detail vertical section on the line y y of Fig. l.

As seenv in Fig. l, the engine B, which may be of any suitable orpreferred construction, is by preference located upon the,a frontportion of the car A.which is provided with front and rearsupporting-wheels, w w', of any suitable kind.

Upon each side of the car a bearing-plate, O, having a perforated upperextension, c', and a bifurcated lower extension, c, is secured to anexterior longitudinal sill, C, of the bedframe. The lower extension, c,receives within the jaws c2 c2 of its bifurcated portion the body of aslidinglink, (l, within the opening of which is received the upper andlower members, c3 c4, respectively, of a journal-box, O3, which membershave in their coincident faces curved recesses, as shown, to receive theend e of the axle E4 of the driving-wheels E. The coincident faces ofthe jaws c2 c2 and the corresponding surfaces of the journal-box areslightly curved, as seen in Fig-i, in the arc of a circle of which theengine-shaft is the center. The link d is provided upon its inner andupon its outer face with washers or guides d, which are secured byscrewbolts d6, the washers projecting beyond the b ody of the link andoverlapping each side' of the jaws c2, as seen in Figs. 4 and 5. Themembers of the journal-box extend at their ends somewhat beyond thefaces of the link in which they are held, and are provided with flangesc5 c5, which embrace the body of the link.

`A spring, cl2, composed of rubber or other suitable material, issecured by pins d4 d5, or other means, within the space between thejournal-box C3 and the base dict' the link. A truss-bar, C4, whichextends across the lower extremity of the bearing-plate O and islmadefast by its ends vto the sill C, serves to give increased firmness tothe bearingplate and the wheel-operatin g mechanism connected therewith.

The upper extremity of the sliding link CZ is connected by apivot-joint, d, with the lower TOO member,f, of a toggle-lever, l theupper membenj, of which is secured by a pivot-pin,f2, to the upperextension, c', of the bearing-plate C. An actuating-lever, J, having itsfulcrum upon the bed-frame of the vehicle, is pivoted at its lowerextremity to a connectingbar, l, which in turn is pivoted to a fixedarm, 71., which projects obliquely downward from the transverserocker-shaft ll, which has its 1o bearings in journal-plates 71', whichare secured to the longitudinal sills C. A fixed upper arm, il?, uponthe rocker-shaft ll, projects in a direction from su eh shaft oppositeto that of the lower arm, 71, and at its upper extremity I5 is pivotedto a bar, G, which extends along the sill C and the bearing-plate C',and is received by its opposite end upon the pivot-pin f3, whichconnects the members f f of the toggle-lever F. Each driving-wheel E has2o upon its outer face a circular grooved bearing or chain wheel, E',which receives motion from the shaft l) of the engine B through themedium of the endless chain K.

It will be observed that the driving-wheels have a broad periphery, topermit free lateral movement in rounding curves without liability todei-ailment. As shown, these wheels are unlianged; but a llange may beemployed when desired.

3o ln the operation ot' the raising and lowering mechanism, which willbe readily under- I pressibility ot' only three-'fourths of an inch l itfollows that the dri ving-wheels cannot,when elevated, be brought int-ocontact with such rail by any jolting movement of the car. \Vhen thelever J is released, the drivingwheels, by their own gravity, descendupon the rail, when a very slight foiwvard move- 5o ment of such leverrenders the engagementot the wheels with the rail rigid and effectivefor all purposes. 'lheinclination ot the ways or jaws similarlyoperates, when the lever .l is thrown backward, to facilitate theelevation of; the drivi11g-wheels.

The lever J, which, as already described, is connected by a series ofarms, bars, and levers with the wheel-carrying link (l, is connectedalso by a chain, l', with a link, Z2, of the brake-chain l, so that whenthe lever .l is thrown forward to thrust the driving-wheels downwardupon the track the brakes L are by the saine movement of the leverreleased from engagement with the supporting-wheels w y1c', and so thatwhen the drivin g-wheels are lifted such brakes will by the samemovement be again brought into contact with such supporting-wheels. Itwill thus be seen that under this construction both the drivin g-wheelsand the supporting-wheels may be wholly controlled by a single operator.

Having described our invention, we claiml. The combination, with a ear,of: an engine which is ixed upon the car, a pair of drivingwvheelsmounted in the frame of the car impelled by such engine and movable inways which are concentric with the axis of the engine-shaft, and acompound lever operable from the en gine-plattorm either to lift thewheels from the track or to hold them in positive and rigid engagementtherewith.

2. The combination, with a car, of an engine mounted upon such ear, apair of driving-wheels mounted upon such car and adjustable up or downin ways thereon, a connection between the driving-shaft of the cngincand the axle of the driving-wheels, and a lever whereby thedriving-wheels are movable either into or out of engagement with thecar-track.

In a car which is provided with a brakerod and with brake-chains andbrakes, the combination of driving-wheels, an engine, a lever which isoperable to adjust such wheels either upon or away from the track, and achain which connects such operating-lever with the brake-chains, wherebyboth the driving-wheels and the supporting-wheels are controlled b v asingle operator.
